1 Claim. (Cl. 16484.5)

The invention relates to new and useful improvements in a tapedispensing device and more particuarly a device for dispensing tapehaving an adhesive on one face thereof.

An object of the invention is to provide a dispensing device for tapewherein the tape drawn from the roll ready for severing is laid over asupporting member and is clamped thereagainst by a cutting blade tofacilitate the severing of the tape by a pull thereon across the blade.

Another object of the invention is to provide a tape dispensing deviceof the above type wherein the supporting member for the tape and thecutting blade are mounted on a frame frictionally gripping theperipheral portion of a tape roll and wherein said frame is moved aboutthe peripheryof the roll by a pull on the tape for stripping the tapefrom the roll.

Still another object is to provide a tape dispensing device of the abovetype wherein a means is provided for preventing the tape; from stickingto the support for the cutting blade after the tape is severed andbefore another tape dispensing operation.

In the drawings which show the tape dispensing device as applied tothedispensing of tape from a tape roll:

Figure l is a view in side elevation of the tape dispensing deviceapplied to a tape roll and showing the manner of holding the roll andstripping of the tape from the roll;

Figure 2 is a view similar to Figure 1 but showing the cutting bladepressing the tape against the support therefor and illustrating inbroken lines the manner of holding the tape while it is pulled acrossthe blade for severing the same.

Figure 3 is a view showing a longitudinal sectional view through thetape dispensing device with the cutting blade and the cut end portion ofthe tape in raised position preparatory to gripping the tape end foranother dispensing operation;

Figure 4 is a sectional view on the line 4, 4 of Figure 2;

Figure 5 is a sectional view on the line 5, 5 of Figure 2;

Figure 6 is a perspective view showing the tape dispensing deviceremoved from the tape roll and the cutting blade raised on the supportagainst which the tape is clamped for severing.

The improved tape dispensing device as illustrated in the drawings isapplied to the dispensing of tape from a tape roll which includes arigid ring shaped supporting base member 1. The tape 2 is provided withan adhesive on the inner face thereof and is wound spirally upon saidsupporting base. This is a well known form of tape roll and need not befurther described. The tape dispensing device includes a base plate 3which extends transversely across the periphery of the tape roll. Ateach side of this base plate 3 are depending side members 4, 4. Eachside member is curved outwardly as indicated at 5. The base plate 3 isthe same width as the tape with a slight clearance at each side and thedepending members 4 frictionally grip the side walls of the tape roll.These side members preferably extend inwardly a short distance beyondthe supporting base member 1.

Thepside members 4, 4 are wider than the base plate 3 and are providedwith upstanding ears 5, 5 through which a rod 6 extends. At the front oradvanced side of the base plate 3 is a supporting plate 7 which inclinesdownwardly slightly. This supporting plate is shown as formed integralwith the base plate 3 and is adapted at its forward edge to contact withthe outer face of the tape roll. A cutter supporting member 8 isprovided with a cutter 9 depending from the free edge thereof and thelower edge of the cutting blade is serrated as indicated at 10 in thedrawings. This blade supporting plate 8 has depending members 11 whichare provided with openings to receive the pivot rod 4. The ends of thepivot rod are headed so as to retain the depending members 11 and permitthe blade carrying member to swing about the axis of the rod as a pivot.The blade supporting member 8 is out along parallel lines so as toprovide a finger 12 which is integral with the blade supporting plateand is normally bent downwardly into the space beneath the bladesupporting plate. The blade supporting plate is also provided with ribs13, 13 which extend lengthwise of the plate and strengthen the same.

When the tape dispensing device is placed on the tape roll the tape endis carried around the rod 6 and is drawn over the supporting base plate3. A pull on the tape as illustrated in Figure 1 will strip the tapefrom the roll and it will also cause the dispensing device to move alongthe peripheral portion of the roll to the same extent as the tape isstripped from the roll for dispensing. When the proper amount of tapehas been drawn oif then the tape end 14 is laid on the supporting plate7 as shown in Figure 2. The cutting blade is then lowered into positionso as to engage the tape and pressure is applied to the blade so as totightly clamp the tape against the supporting plate 7 therefor. Thestrip is then pulled across the blade in the usual manner for severingthe same. One of the principal features of the present invention is thissupporting plate against which the tape to be severed is clamped by thecutting blade. With this supporting plate a tape of plastic, linen, orany other well-known material, may be very readily severed.

The blade supporting plate 8 is provided with the finger 12 which liesin the space directly beneath the plate and in rear of the blade so thatthe tape is prevented from becoming detached from the blade and stickingto the underside of the supporting plate therefor. This retains thesevered tape in the position shown in Figure 3 when the blade supportingplate is raised. The tape end is readily accessible, therefore, forfinger engagement so as to pull off a desired length of tape for use.

It is obvious that the essential features of the tape dispensing devicemay be used with various types of tape roll supporting structures and itis also obvious that minor changes in the details of construction can bemade without departing from the construction as set forth in theappended claim.

I claim:

A tape dispensing device comprising a frame having members frictionallygripping the opposite side portions of a tape roll and movable about theperiphery of the roll by a pull on the tape for stripping the tape fromthe roll, a rod carried by said frame and extending across the roll overwhich the tape is inverted and drawn, said frame having a supportingmember extending along the tape roll over which the inverted strippedend portion of the tape is laid, a plate pivoted to said frame and acutting blade at the free end of said plate extending at an anglethereto and having a serrated edge, said plate terminating short of thesupporting member whereby the tape may be clamped against the outer faceof said supporting' member and the tape severed by a pull on the tapelengthwise of the blade.
